Drug Test in 2 days! Need Help/ advice?

So I have a drug test in 2 days and I havent smoked for roughly 8 or 9 days. Last time I smoked I took 2 hits. I used to be a daily smoker a week before i took the 2 hits. I know thc stores in your fat cells, I recently measured 7% body fat. I'm pretty skinny. Since the last time i smoked (2 hits), I've been drinking tons of water, went to the sona yesterday, played basketball today(sweated my *** off) and going to the sona tommorow. I need to know my odds of passing this drug test which is in 2 days. So anyone with any or a lot of experience from taking drug test or drugs expert please help. First drug test and I need to pass!
